The wetted area, shaped by the aspect ratio in aerodynamics, characterizes the surface of an aircraft that interacts with the surrounding air. This metric, influenced by the wingspan and aspect ratio, is vital for assessing aerodynamic performance. A higher wetted area generally implies increased skin friction and drag. The formula to calculate Wetted area as follows:
Where:
- is the wetted area,
- is the Lateral plane span in m,
- is the aspect ratio in Lateral plne.
